Iranian Ballistic Missile Capabilities
Iran is successfully
developing ballistic missiles
with the aim of giving the
Islamic Republic the
capability to deliver warheads
well beyond its borders;
But the worst-case scenario
ten years ago about Iran
being able to develop an
ICBM capable of striking the
US within five years has not
materialised.

Simorgh satellite launcher
development is part of an
ambitious space program
with the goal of placing a
man in space by the end
of this decade.
Inaugural launch
scheduled for next year.

Iran is the only country to have
developed a missile of the Sajjil2’s reach without first having
developed a nuclear weapon.

But, they could be used as a terror weapon, designed to sow fear and

Nuclear warheads have
a much stronger
strategic logic, if Iran
can make a bomb small
enough.
The most likely delivery
platform for a notional
Iranian nuclear weapon
would be the Ghadr-1,
or possibly the Shahab3.
After development, the

Development of the Sajjil-2
may have been prompted by
concerns that a one-ton,
first generation bomb
design could not be
delivered to Israel by the
Ghadr-1, unless launched
from positions along the
Iran-Iraq border, where the
launcher and missile would
be vulnerable to preemptive strikes.

Status of Iran’s Missile Industries
Iran has invested heavily to establish an indigenous production
capacity
– Considerable success to date; but still dependent on foreign sources for
key components, materials and manufacturing equipment
– Solid-propellant industries more capable than Liquid-fueled counterparts
• Cannot develop new liquid-fueled engine indigenously
• Could produce larger solid-propellant motors with minimal foreign assistance
Established disciplined, robust engineering management
processes which enables future developments
– Capable of introducing moderately sophisticated countermeasures
Missiles will remain inaccurate
Iranian Ballistic Missile Capabilities
Future Missiles: What and When ?
Liquid-Propellant missiles constrained by limited technology
base; no new engine development possible
• Intercontinental Missile (ICBM) would be more than 100 tons
• Available engines sufficient for future space launch vehicles
• Man in space by 2019?
Three stage Sajjil missile possible (3500km)
• Two to five year flight test program
Second generation Intermediate Range Missile (IRBM) at least
six to ten years away, based on experiences elsewhere
• Four year flight test program – minimum time
Based on Iran’s history, IRBM development before an ICBM
Notional, 9000km ICBM at least a decade away

Joint Development Efforts?
Iranian Ballistic Missile Capabilities
BM-25 (Musudan, R-27)
Russian R-27 developed as a submarine launched missile
• Capable of 2400km range, with 650 kg warhead
• Enhanced performance propellants (UDMH-N2O4)
Must be modified for use as a road-mobile missile
• Structural reinforcements required
• Oxidizer very sensitive to temperature changes;
missile must be thermally protected
Musudan has been lengthened, and reinforced?
Range-Payload performance similar to original R-27
• Enhanced accuracy possible if state-of-the-art
navigation units incorporated, but unlikely
Musudan/BM-25 is a NEW MISSILE; has not been flight
tested!!
